This evolutionary process, still making its impact felt today, became increasingly pronounced in the years between 1910 and 1930. Even before the first blues recordings were made, the blues idiom began filtering into the mainstream of American parlor sheet music, under the influence of Tin Pan Alley songwriters such as W. C. Handy.
Wind energy supplied 4.7 percent of the total electricity generated in the U.S. in 2015, enough electricity to supply the equivalent of all electricity demand in Colorado, Oklahoma, and Kansas. Solar energy, including utility-scale and distributed solar, generated 0.94 percent of all U.S. electricity in 2015. The emerging opportunities in American wind power will be on display at this yearâs WINDPOWER Conference & Exhibition in New Orleans, May 23-26.
By itself, electricity is an exceptionally clean form of energy but we have to consider how it is generated. Today, about 70% of U.S. electricity is produced from fossil fuels (about 50% from coal, and 20% from natural gas). Nuclear power accounts for another 20%, leaving about 10% coming from renewable resources like wind, water and solar.
